5.

Consistency and Standards
Design should follow the guidelines and conventions of similar systems,
applications, or websites
Users should be able to make inferences about labels and terms by drawing
from their experiences with similar interfaces and systems

6.

Error Prevention
Design to prevent errors

7.

Recognition Rather than Recall
Keep the amount users have to remember to a minimum
Don’t expect users to remember specific, detailed information
about system
Interface should be designed to allow users to easily recognize
or intuit functionality

8.

Flexibility and Efficiency of Use
Design should accommodate both experienced and
inexperienced users

9.

Aesthetic and Minimalist Design
Design should include only relevant, minimally needed information
Unnecessary information:
Makes it harder to see important information
Decreases design’s overall usability

10.

Help Users Recognize, Diagnose, and Recover from Errors
Use plain language to indicate problem and suggest solution
Error messages should:
Be clear, specific, easy to understand
Be meaningful to the user
Provide immediate feedback and specific guidance on how to recover
from the error

11.

Help and Documentation
Documentation should be:
Helpful and relevant in the user’s context
Focused on the user’s task
Easily searchable and accessible

12.

Exercise Reflection
What have you learned from checking your design against all
ten principles combined and how will you improve your design
as a result?
